The short answer
For most founders, yes, and that is what makes it risky. Your salary comes from the company, a large chunk of your net worth is its equity, and if you took a home loan on the strength of that salary, your house is leaning on it too. When one thing goes wrong, they can all wobble together. That is concentration hiding in plain sight: it looks like several assets, but they share a single point of failure. The fix is not to quit or sell everything, it is to make sure at least some of your safety net does not depend on the company at all, like liquid savings or investments in unrelated assets. Zerodha Varsity's personal finance module is a plain-language start on how to think about this. This is general education, not advice, so weigh it against your own circumstances.
